Radio Control Systems 遥控系统By Paul Williams.Article posted 1st March 2008.Problems with radio control systems seem to plague FE boaters. This is not surprising, given the harsh environment these delicate electronic components have to tolerate. High humidity, high temperatures, motor noise and vibration combine to make life difficult for receivers and servos. 遥控系统的问题对于竞速船是个麻烦事，因为这个精致的电子设备必须忍受恶略的环境。
高湿度，高温度，噪音，震动很容易缩短接受和舵机的寿命。
Blaming the environment, however, cannot mask the fact that many FE boaters do themselves no favours when fitting out their radio system. Some of the cardinal sins I've seen committed include cutting the original aerial wire. Do not do this. The aerial is meant to be a fixed unbroken length. Altering the tuned length and introducing connectors immediately compromises the receiver's ability to pick up a clean signal. Run the aerial wire vertically up and out of the boat through a length of thin plastic tube. 然而，抱怨环境是解决不了问题的。
我曾经指出过，不可以减短接受天线，改变天线长度或者加上一个连接器，立刻就会影响接受器接受信号的能力。
让天线竖直，并且伸出舱外。
Cheaper radios often have very long aerial wires. Don't be tempted to coil up the excess length of aerial inside the boat. Run the whole length up and out, securing the aerial end to the base of the aerial tube. When the boat is running, the slipstream will pull the aerial into an open loop. 廉价的接受一般会有很长的天线。
不要把天线缠绕的放置在船内。
一定要让天线伸展开来，并且用天线座安装好，高速气流可能会把天线吹开。
Racing boats really only need two channels: on and off, and left and right. They usually don't require huge range like a model aircraft. The best advice regarding radio systems is to buy the very best you can afford. If it's a choice between spending out on a better, more reliable radio or a more powerful motor, consider this: the more powerful motor will smash your boat into a wall or other object harder when the radio fails! Avoid really cheap radio sets. They don't have the range or signal processing/interference rejection of more expensive sets and are a false economy. It's quite easy to spend many hundreds of pounds on a high speed model. Do you really want to risk that kind of investment by skimping on a decent radio set? 竞速船只需要两个通道：油门和方向。
他们不需要空模那么多通道。
去买个你可以负担的起的设备。
如果在电机和控之间投资，好电机和不好的控配合，只会在失控时，让你的好电机更快把你的船撞到墙上去，一定不要用不好的控。
不要用不好的控，它会把你昂贵的投资给毁了。
A cheap radio may work faultlessly when testing on your own, but in a race may glitch like crazy in the company of another 7 or so radios. Smacking into another competitor's boat because your radio can't cope will earn you no friends and will probably get you disqualified. 总而言之，不要用便宜，不好的控。
40Mhz or 2.4GHz?There are two frequency bands available to surface models in the UK: 40 MHz FM and 2.4GHz. 40MHz is the "traditional" frequency band and has been in use for many years. 40MHz sets run on a single pre-determined channel or frequency, set by either changing the crystals in the receiver and transmitter, or by dialling in the required channel on a synthesised set. 2.4GHz sets constantly hop around the frequency band and can detect and automatically avoid clashing with other 2.4GHz sets in range. There's a lot more to 2.4GHz than this and Google is a good place to start if you want to know more. For simplicity's sake, all we need to know about 2.4GHz is that you don't need to worry about frequency control anymore and that the aerials are conveniently very short and thus easier to install and less likely to be damaged. 在美国基本有两个波段供水面模型使用：40MHz和2.4GHz. 40MHz是一种被使用很多年的传统波段。
40Mhz在一个特定的频道工作，改变频率通过更换接受和发射晶体，或者通过同步设备完成。
2.4GHz在各个波段挑转，可以发现并自动避免和其他2.4GHz产品重频，你可以通过搜索获得更多的资料。
简单来说，2.4GHz让你不再为重频而担忧，并且它们接受的天线很短，方便安装，不易损坏。
Unfortunately, I'm now very hesitant to recommend 2.4GHz for fast electrics. My own experience of 2.4GHz was not a happy one, and after a near disaster the one and only time I tried it in a race (total loss of control and a failure of the radio to fail-safe) I sold my 2.4GHz Futaba 3GR set on ebay and went back to 40MHz. That said, there are many FE racers who are very happy with 2.4GHz. 不过，我并不推崇2.4GHz产品。
我的经验，它让我在一次比赛中差点完蛋，然后我就把它给买了，并重新用回了40MHz。
但，很多赛手还是对2.4G产品乐此不疲。
（译者：差点损失就不用了？我们这些新手由于各种原因沉了多少船，还在不断努力。
）In my opinion the jury is still out on whether 2.4GHz really works reliably enough for powerboats, given that powerboats tend to throw huge amounts of water into the air from propellers, turn fins and rudders, and the one thing a very high frequency signal has trouble punching through is a dense, attenuative medium like water. 我对2.4GHz的产品对于高速电船是否可靠有几个意见。
